Abstract: PURPOSE:To realize fast, high-function printer processing by providing the 1st and the 2nd microprocessors and coupling a control means and a subordinate control means through buffer memory which is accessed by the both, and putting both microprocessors in partial charge of control over a printer device. CONSTITUTION:A subprocessor 8 outputs a signal L to a terminal PROG to hold a terminal Q of an HRPFF13-1 at H.

Title: Carry look-ahead circuit
Inventor: KAMAYA YUKIO
IPC: G06F7/50
Filed: 1986-03-20
Abstract: PURPOSE:To avoid duplication of the same function to obtain an integrated circuit where the power and the area are reduced, by using common logic as jointly as possible and making two carry look-ahead circuits CLA into one block with respect to calculation of the CLA for two kinds of input carry '0' and '1'. CONSTITUTION:When input carries are '0' and '1', 4-bit CLAs 40 and 41 are constituted as shown in figures, but parts surrounded with alternate long and short dash lines coincide with each other completely with respect to constitution. With respect to a function, these parts coinciding with each other are the common part of calculation of S<0>3 and S<1>3 for generation and propagation of the sum signal of the i-th input bits and carry signals from low-order bits and those of the sum signal and carry signals from low-order bits. Though the sum of the number of gates in CLAs 40 and 41 is 63, a CLA 4C where the common part is constituted as one circuit has 41 gates while holding the same function and the number of gates is reduced by about 35%. If this CLA 4C is used to adopt the carry selecting method, the number of gates is reduced and the area of the circuit is reduced.

Title: Winder control device
Inventor: TOMIOKA TAKASHI
IPC: H02P5/46
Filed: 1990-03-12
Abstract: PURPOSE:To unnecessitate resetting work labor due to an emergency stop so as to improve productivity in paper making industry by constructing a winder control device in such a way as to operate a winder continuously without bringing it to an emergency stop at the overload time of a motor and a thyristor control device due to the frequent start-up of the winder as well as to accelerate the winder up to the set speed. CONSTITUTION:When the heat capacity of a motor 12 and a thyristor control device 10 exceeds the limit capacity, the speed of a winder 11 is held to lower the thermal load capacity of the motor 12 and thyristor control device 10 every moment and thereby to enlarge difference between the heat capacity and thermal limit capacity of the motor 12 and thyristor control device every moment. As a result, the margin of heat capacity for reacceleration is enlarged in the motor 12 and thyristor control device 10. The heat capacity at the time of reacceleration from the present held speed to the set speed is therefore computed on one side, and when this heat capacity is lower than the thermal limit capacity of the motor 12 and thyristor control device 10, the winder 11 is reaccelerated up to the set speed.

IPC: G06F15/16
Filed: 1986-03-20
Abstract: PURPOSE:To eliminate the waste to consume time due to an unnecessary polling by making mutually different the period of a polling signal sent from the process to execute the data communication mutually to an opponent side. CONSTITUTION:When the time limit t1 of the timer of a process 11 is shorter than the time limit t2 of a process 21 and the timer 22 of the process 21 receives the polling signal from the process 11, resetting is executed by the output of a detecter 23 two times when the signal is received and when a response signal (ACK signal) is returned to the process 11 in response to it, and finally, counting is started from the time to return the response signal. Since the time during from the time when the polling signal is received to the time when the response signal is returned, is significantly short, the time is neglected and then, t1<t2 is obtained. Consequently, next when the polling from the process 11 is executed after t1 is elapsed, the timer 22 of the process 21, before it never arrives at the time limit t2, is reset by the output of the detecting device 23.
